BETEX® INDUCTION HEATERS Mounting & Dismounting

Why use induction heating?

Demagnetization Reliable demagnetization is very important for bearings and transmission parts. The proven quality of BETEX® induction heaters guarantees maximum demagnetization (< 2A/cm). This has a major impact on the service life of for instance bearings and gear wheels. Energy efficient All BETEX® induction heaters are energy efficient in comparison with traditional methods.

induction heating as the best practice for bearing mounting. Multifunctional, for mounting and dismounting We offer solutions for Mounting (low- frequency) and Dismounting (medium- frequency). For bearings, gear wheels, Temperature and/or time Smart electronics ensure optimum control during the heating process. These automatically regulate the most efficient use of power and ensure even and rapid heating. No extra steps are necessary. Explosive heating is impossible (no discolouration or pitting of material). bushings, couplings, etc. Controlled heating

Induction heating is a superior, fast and controlled heating method. It is a safe and environmentally-friendly alternative to traditional heating methods such as ovens, oil baths or blow torches. These methods generate smoke, fumes or oil waste and are hazardous for your personal safety and a healthy working environment. It is common knowledge that a correct mounting method extends the bearing life. Controlled stress-free heating prevents unnecessary damage, while retaining the original bearing lubrication. Ideal for sealed bearings (2RS-ZZ). Bearing manufacturers recommend controlled

New generation with smart technology The heating process is displayed in a clear graph on a touchscreen. There is a log function to save or export data. A work log can be created as evidence. Thanks to the double temperature sensor it is possible to heat stress-free with preset values (ΔT). For more control and stress-free mounting Thanks to the ΔT monitoring, it is possible to measure the internal and external temperature of a workpiece with 2 temperature probes. Thus the maximum preset temperature difference between 2 points can never be exceeded. This achieves even and uniform heating and prevents material stress.

Operating principle The heater works by inducing a (low-frequency) current in the workpiece to be heated. This is achieved by incorporating the workpiece as a secondary winding in a transformer. The primary winding is connected to the mains power by means of an electronic control. The magnetic field induces a high current (short-circuit current) through the workpiece, which consequently becomes hot. The workpiece is automatically demagnetized after each heating cycle. Difference between low-frequency and medium-frequency

• Low-frequency: slow heating, great heat penetration depth • Medium-frequency: fast heating, shallow heat penetration depth Heating times are subject to the relationship between: • Dimensions and weight • Temperature and material • Available power
